Hi, the extruder is now working
I have made the first layer calibration- came out very good
But when i will start a print came this message:

28.6.2021, 17:04:24 Warning: M73: Command is not supported
Warning: M73: Command is not supported

@revolution, either ignore that warning; or configure your slicer not to generate M73 commands; or upgrade to firmware 3.3.

Hi, now i have upgraded to 3.3
When i will print something i get this message

28.6.2021, 18:06:15 Cancelled printing file 0:/gcodes/gearr_0.2mm_PLA_MK3S_18m.gcode, print time was 0h 2m
Emergency Stop! Reset the controller to continue.
Error: Homing failed
Can i Post videos?

[Phaedrux]

Yes you can post videos.

When do you get that error?

Please post your homing macros as well as your slicer start gcode so we can see what is going on when you start a print.

What do you have in bed.g and homeall.g?

Can you please also post the slicer start gcode section?

Can you describe what I'm seeing in that video?

In the Video you see starting a Print, the leveling and Then the Print should starting but then the extruder goes only on the Home of x and nothing happens
I Hope you know what i mean?

M98 P"homez.g" ; homeall is the same as homez

Ok, what's in homez.g then?

It looks like you get through the leveling portion. Then the print should be starting, but it moves very slowly to the left. If that is from the sliced gcode section please share either the slicer start gcode section or share the first 50 lines or so of a sliced gcode file.

Everything the printer is doing is just gcode commands. So being able to see what those commands are is important for understanding what's actually happening.

Would you say that the slow movement occurs here? F1000 is about 16mm/s so quite slow. F6000 would be more appropriate for a travel move.

There are a few things in your slicer start gcode that aren't compatible with reprapfirmware. What gcode flavor do you have set for PrusaSlicer?

M115 for instance just reports the current firmware version.
G28 W would likely just run homeall.g with no changes.
G80 isn't a supported gcode at all. To do mesh compensation in RRF you use G29.

M98 P"current-sense-normal.g" ; Ensure the current and sensitivity is set for homing routines.

Can you post those two macros as well for full disclosure?

Also, at what point in your video are you getting the short to ground error on driver 3? Driver 3 appears to be your extruder.

Are you able to extrude into free air by heating the hotend and commanding extrusion from DWC or paneldue?

Now i have solve the problem:
i have changed in Prusaslicer the Firmware G-Code Typ to "RepRap/Sprinter"
Then i add this customised Start G-code

;
G0 X60 Y-3 Z80 ; move extruder above bed, keep extruder in front for cleaning and checking
;
M104 S160 T0 ; pre-heat extruder to 160°C
M140 S[first_layer_bed_temperature] ; this will take the layer 1 temperature for bed 0
M190 S[first_layer_bed_temperature] ; wait for bed temp
;
G29 ; mesh bed leveling using defined mesh grid
G0 X0 Y-3 Z0.6 ; go outside print area

M104 S[first_layer_temperature] ; set extruder temperature
M109 S[first_layer_temperature] ; wait for extruder temp
;
; =========================================================================================================
;
;
M98 P"0:/sys/primeLine.g" ; execute primeline macro
;
G92 E0.0 ; set extruder position
;
M572 D0 S0.07 ; set pressure advance

Now it works!
